TR19 Grease certificate software
TR19 Grease certificate software: the certificate your client's insurer actually reads
When a kitchen has a fire, or an insurer asks for evidence, the certificate is the document that gets read. It has to be clear, it has to be correct, and it has to come from you.

Field by field
What each line on the certificate tells the reader
| On the certificate | What it tells the reader |
|---|---|
| Your firm's name, address, company number and logo | Who did the work. The certificate carries your brand, not ours. |
| Site cleaned and system | Which kitchen and which system, so there is no doubt about what the certificate covers |
| Date the clean was done | When the system was last brought back to a clean state |
| Certificate reference | A unique code anyone can quote to your firm to confirm the certificate is genuine |
| Report reference | Links the certificate to the full post-clean report behind it |
| Mean post-clean deposit | The average grease thickness after cleaning, in microns, from the readings |
| Result | Pass or fail, in one word |
| Next clean or inspection due | The date the next visit is owed |
| How the frequency was set | Which table was used and why - for example, the usage level of the kitchen |
The result line puts the three things a reader looks for side by side: the mean deposit, the result, and the next date due.
Proof it is genuine
Why a reference number matters
There is a real problem in the field: a generic certificate gets printed off, re-dated and shown as if it were new. A certificate is only worth something if it can be checked.
Every certificate carries its own reference, and its wording tells the reader to quote that reference back to the firm that issued it. The same reference ties the certificate to its report and appears on the invoice in Xero, so the office can trace any certificate to the job, the readings and the bill.
The check
Certificate → report → invoice
One reference runs through all three. A copied or re-dated certificate fails that check.
The evidence behind it
The certificate never travels alone
Behind every certificate sits the full post-clean report. In the sample it runs to 14 pages:
- Readings before and after at each location, graded from Very Dirty to Clean
- Before and after photographs from nine locations
- A schematic of the system
- A description of what the system includes, and a completion checklist
See how the report is produced in our guide to TR19 Grease report software.
How it gets made
From readings to certificate, without the sums
Readings on the phone
The engineer records the readings, along with which frequency table applies to the kitchen.
Mean worked out
The mean deposit is calculated from the readings, so nobody adds it up by hand.
Next clean set
The next clean date follows from the engineer's choice of table.
Reviewed and sent
The office reviews and sends it. The invoice goes to Xero and the next clean appears in the planner.
Certified. Scheduled. Paid.

Questions
Questions firms ask
Can the certificate carry our logo and details?
Yes. Your firm's name, address, company number and logo appear at the top.
Does the certificate show the next clean date?
Yes. It shows the next date due and how the interval was set.
Can a client check that a certificate is genuine?
Yes. Each certificate has a unique reference that the client can quote back to your firm.
Is the certificate approved by BESA?
No. TR19 Grease is BESA's specification. The software produces certificates laid out to follow it, and Smart Solutions is not affiliated with BESA and is not endorsed by it.
Is our data kept separate from other firms?
Yes. Every firm gets its own database, set up for that firm alone. No database is shared, so your clients, sites, reports and photographs never sit alongside another firm's records.
